What is the life expectancy of the RenewAire ERV energy exchange core?

The RenewAire core was designed to perform with a service life of 20+ years. Since introduction of the technology in the early 1970's, millions of these cores have been operating throughout the world with virtually a zero failure rate. Moreover, it has been well documented that both heat and moisture characteristics of RenewAire cores have not changed significantly when measured over time.

Among our competitors' desiccant-coated heat wheels, on the other hand, few are expected to perform optimally for more than 10 years.
